To aZl whom it may concern: Be it known that I, MARTIN S. KARrEiv,

a citizen of the United States, residing at bination sofas and beds, or combination couches and beds, in which the foldable mattress-frame is normally housed within the main frame beneath the seat of the sofa and equipped with a flexible bed-bottom, or wire mattress, the parts being so related as to afford room between. the sections of the folded mattress for the beddingthat is, the mattress pad, bed linen and covers.

My primary object is to provide an improved construction of the character indicated which will operate in an improved manner, and whichmay be produced at very moderate cost. p

The invention is illustrated in its preferred embodiment. drawings in which- Figurel represents a sectional view of my improved sofa-bed in the open orbed position; Fig. 2, a broken sectional view taken as indicated at line 2 of Fig. 1, and'showing the manner in which the intermediate bed section employed is mounted on the pivotal portion of the forwardly swinging sofa-seat; Fig. 3, a broken section taken as indicated at line 3 of Fig. 1 and showng a detail of thepivotal mounting of the intermediate bed'section; Fig. 4, a section similar to Fig. 1, butshowing the structure in sofa form; Fig. 5, a section taken as indicated at line 5 of Fig. 1, and showing a detail of the manner inwhich the front bed'section is foldably or eollapsibly connected with the sofa seat; Fig. 5*, a section taken as indicated at line 5 of Fig. 1; and Fig. 6, a horizontal section taken as indicated at line 6 ofFig. 1.

In the construction illustrated, A represents a main frame; B, a stationary back supported by the end standards of the main frame; O, a seatpivotally connected at its front portion'with the front portion of the main frame; and D, a foldable bed normally housed in folded condition beneath the seat C and having an intermediate section pivot-- ally connected with brackets, or hangers, carried by the pivotal portion of the sofa seat.

Specification of Letters Patent. Patented June 20, 1911, Application filed May 9; 1910.' Serial No. 560,206. i

The frame A may be of any suitable construction. As shown, it comprises ornamental end-standards 1 which serve as arms for the sofa; and a box-form frame 2 interposed between the .lower portions of said endstandards and comprising end members 3 fixedly secured to the lower portions of the end-standards l and connected by a front piece 4 and a rear member 5.

The-back B is disposed between the rear upper portions of the end-standards 1, be-

ing rigidly connected therewith in any suitable manner.

The seat C comprises a frame and cushion 7 (indicated by dotted lines). The seat is plvotally connected with the main frame, the seat having the base portion of its frame equipped with hinged members 8 which are joined, by pintles 9, to hinge members 10 secured to the front upper corners of the box-form frame 2.-

The bed frame 1) preferably comprises an intermediate section 11; a front section 12, and a rear section 13. The intermediate section 11 comprises end members or bars (shown of angle form) which are connected, by pivots 14, with'hangers 1 5 which are securely attached to the seat frame (3 near the pivots of the seat and normally depend into the front portion of the box 2 when the structure is in sofa form. Each hanger 15 comprises a vertical bar 16 having an inturned end 17 securely fastened to the plvotal port-ion of-the seat frame; and a brace 1.8 so

cured to the longitudinal member of the seat frame at one end and having its other end separated from the free end of the member 16 by a space adapted to receive the end members of the intermediate bed section 11. As shown in Figs. 2 and 3', the end members of the intermediate bed section are spaced from the free ends of the members 16, by washers 19. v

The front bed section 12 comprises a 1on gitudinal member 20 having arms 21 which are connected, by pivots 22, with the adjacent ends of the end members of the .interinediatebed section 11. The rear bed secpivots with the corresponding ends of 1 the end members of the intermediate bed section 11.

The links 28 are joined the links The foldable bed frame just described is equipped with a foldable wire mattress, or flexible bed-bottom 26.

Describing the structure in the open condition, when the seat C occupies an inverted position in front of the main frame, the hangers 15 at such time constitute standards upon which the intermediate bed sec tion 11 is pivotally mounted. The end members 21 of the upper or front bed section are equipped with slides 27 joined by links 28 to the seat frame 6 some distance from the free or swinging edge ofthe seat. to theslidcs 27 by are joined, by pivots 30, to

pivots 29 and The clips'31 secured to the seat frame (3.

end members 2-lof the rear bed section are equipped with slides 32. Links 33 connect said slides to the front portion of the boxform frame 2. The links'33 are connected at one end, by pivots 34 with the" slides and at the other end, by pivots 35, with clips or bars 36 secured to the inner surfaces of the end members 3 of the box-form frame 2. The members 16 forming part of the supports for the intermediate bed section are; connected by the links 37 with the links 33, the front ends of the links 37 being joined by pivots 38 to said members 16 and the rear end of said links being joined by pivots 35) to the intermediate portions of The links. 28 are joined by links 40 to the links 37 near the pivots 38, the front ends of the links 10 being connected by )ivots 41 to the links 28 and the rear ends )eing connected by pivots 42 to the links 37. The detail of the connections between the links 37 and l0 and the supporting members 16 is shown in Fig. 5. Coil-springs 4L3 connect slides 32 to clips 44 attached to the pivotal portion of the rear bed section 13. Springs 45 connect the slides 27 with clips portion of the front springs aid in the operation of unfolding and elevating the bed, as will be readily understood.

The'free, or swinging, edge of the seat (3 is equipped with folding legs 47.

The operation will be readily understood from the foregoing description. The bed is made up while the structure. is in the open position shown in Fig. 1, the bedding being properly secured to the foldable bed 7 frame, and the structure is then converted to sofa. 't'oru'i by swingingthe seat rearwardly to the position shown in Fig. 4. When the seat is swung to the folded position, the links 33 are swung rearwardly through the medium of the links 37, the slides 31 moving rearwardly along the end members 24. of the rear bed section. During this movement, the links 28 are swung toward the free edge of the sofa seat, the slides 27 moving toward the member 20 of the front bed section, this section are caused to approach each -vated position shown in action occurring through the operation of the links 40. During this movement, also, the supporting members 16 of the intermediate bed section are carried to the vertical depending position within the front portion of the box 2, the joint at the pivot 25 collapsing downwardly, while the members 16 are being carried to a plane so as to overlap the outer or upper portions of the end members of the intermediate bed section 11. That is to say, while the pivots 14: are being carried from the position shown in Fig. 1 to the position shown in Fig. 4, the outer ends of the end members of the intermediate bed section and the supports for the intermediate bed section, relatively speaking, approach each other, or fold with relation to each other. After conversion to sofa form, the rear or lower bed section occupies the position in the lower part of the boxform frame 2, where it may rest upon' stops &8, while the front bed section 12 is spaced above the rear accommodate the folded bedding. In the folding operation, the seat and front bed other somewhat, as will be readily understood by comparing Fig. 1 with Fig. 4. In converting from sofa form to bed form, it is only necessary to swing the seat from the position shown in Fig. 4: until it occupies an inverted position in front of the sofa, as shown in Fig. 1. During this operation, the links 37 and 40 operate to actuate the links 33 and 28, thereby moving the slides 32. The unfolding operation is assisted by the coil springs 13 and 45 (one pair would sutlice), which were placed under tension in the folding operation. It will be noted that in the operation of swinging the seat to the open position, the supports 15 carry the pivots 14: of the intermediate bed section to the ele- Fig. 1, and during this movement the intermediate bed section is swu'ng on its pivots 14;, while at the same timethe slides 27 and 32 are actuated to ele vate the front and rear portions, respectively, of the front and rear bed sections. In the open condition of the structure, the bed occupies an extended position in front of the sofa-back, and the construction is such as to prevent any possibility of collapse whilein the open, position.

"he foregoing detailed description has beengivcu for elearness of'understanding only,'and no undue limitation should be understood therefrom, but the appended claims should be construed as broadly as iermissible in view of the'prior art.
